This address is a suite or unit (STE 900). Organizations that share one are often clients of the same office-services firm, accountant or registered agent rather than related to each other.

We match the street line and ZIP code as the IRS gives them, ignoring case and outer spaces and nothing else, so "AVE" and "AVENUE" count as different streets and this list can miss some. A shared address can mean related organizations or a shared office, but it can also be a registered agent, a mail drop or a service provider holding mail for unrelated clients. It is not, by itself, evidence that two organizations are connected.

As filed on the 2025 return. The filer continues this part on Schedule O, which is not shown here.

Officers and directors · 2025

As listed in Part VII of the 2025 return, in the order the filer printed them. Each return names its own; this is not a roster the organization keeps with us.

Compensation is as filed in Part VII: reportable pay from this organization and from related organizations, other compensation, and hours per week. The total, marked calculated, is our sum of the three dollar columns, with a blank column counted as $0; the form itself has no total. On a Form 990-EZ the columns are Part IV's instead, and on a Form 990-PF Part VIII's — compensation, contributions to benefit plans, and expense account — and the total sums those. A Schedule J breakdown is as filed: base pay, bonus, other, deferred compensation and nontaxable benefits from this organization, with any from related organizations beside each, and the filer's own total. It is shown with the Part VII listing of the same name on the same return. The form gives no key between the two, so that pairing is ours, and is marked matched by us. Earlier years are each on their own filing page.

Nonprofiteer parses Forms 990, 990-EZ and 990-PF, in a window of recent tax years. These returns are recorded from the IRS e-file index, so their figures were extracted by that index rather than read from the return here — treat them as a different source from the filings above, not as more of the same record. A dash means the index carries no figure; Form 990-T listings carry none at all. Showing the 10 most recent; the API carries the rest.
